DNMG150408 T5115 indexable insert for turning — CVD-coated carbide, rhombic 55° (Tungaloy)

The DNMG150408 T5115 is an ISO-standard indexable insert engineered for productive external and internal turning of cast iron components, offering a balance of wear resistance and edge stability for reliable workshop performance.

• CVD-coated carbide grade T5115
• ISO rhombic DNMG 55° geometry
• Double-sided chipbreaker, cylindrical hole
• 0.8 mm corner radius for consistent finish

High productivity through controlled chip formation

The combination of a double-sided chipbreaker and a central cylindrical hole produces predictable chip flow and secure clamping, which contributes directly to cycle-time reductions on turning operations. The CVD-coated surface increases wear resistance of the carbide substrate, extending tool life under intermittent and continuous cuts. For machining cast iron, this universal grade offers an advantageous mix of stable cutting edge and abrasion resistance, reducing unexpected tool changes and supporting consistent production runs.

Precise geometry for dependable fit and surface quality

The rhombic insert with a 55° lead angle provides versatility for both external profiling and light internal turning while maintaining access in constrained geometries. The 0° relief angle and an insert thickness of 4.76 mm ensure stable seating in the pocket; the 0.8 mm corner radius supports a balance between edge strength and achievable surface finish. ISO compliance of the insert shape and hole pattern simplifies holder selection, but final compatibility depends on holder form, clamp type and tolerance class.

Practical advice for selection and application

Choose the chipbreaker and grade to match the workpiece material, stability of the setup and cutting parameters: the T5115 grade is optimised for cast iron and performs well where a blend of longevity and edge security is required. The complete system comprises the insert, a matched external holder or boring bar, a backing pad and suitable clamping screws; correct assembly and torque settings are essential to fully exploit the insert’s performance. If process stability is limited, prefer conservative depths of cut and incremental feeds to preserve the cutting edge.

FAQ

What materials is this insert optimised for?
The T5115 grade in the DNMG150408 insert is optimised for cast iron machining, combining abrasion resistance with edge stability for consistent results.

Can this insert be used for internal turning as well as external turning?
Yes, the rhombic 55° geometry and double-sided design allow use in both external and light internal turning applications when paired with an appropriate holder.

How does the CVD coating benefit production?
A CVD-coated surface on the carbide substrate increases wear resistance under abrasive cutting conditions, which helps the insert maintain performance over longer tool life and supports uninterrupted production.

What determines compatibility with a holder?
Compatibility is set by insert form, relief angle, tolerance class, fixing method, size and thickness; confirm these dimensions against the chosen holder before use.

Is the insert reversible and how many cutting edges are available?
The double-sided format provides multiple cutting edges per indexable insert; turning the component to the next edge restores cutting geometry without regrinding.
